1 AFPAEATUS FOR ELECTRICAL STEBILIZATIGN OF FOOD.

Specification of Letters Patent.

Patented July 3, 12%"3.

Application filed (Dctober 7, 1916. serial No. 124,262.

To all whom'z'v' may concern:

Be it known that T, JACOB Hanssnn, citizen of Norway, residing at Christiania, Norw ay, have invented new and useful Improvements in Apparatus for Electrical Sterilization of Food, of which the following is a specification.

It is a well-known fact that foods are sterilized by being treated with electricity, for instance with alternating current of a After such a treatment the goods may be stored for a longer time in a fresh condition. Specially for killing bactiria on split cod the electrolyzation is suita le.

The present invention has for its object to provide a simple and suitable apparatus of the kind referred to and is illustrated in the accompanying drawings, in which:

Figure 1 shows the whole apparatus in side view.

Fig. 2 shows on a larger scale a cross section on the line TT in Fig. 3, seen in the direction of the arrows at the section-line.

Fig. 3 is a part of a side view of the apparatus.

The fish is thrown into a hopper -1 (Fig. 1) and passes down into an inclined channel 2 forming a continuation of the hopper. The treatment with electricity takes place during the passing down onthe bottom 5 of the channel 2 during theshort length of time of passing by and between a number of contact springs 13' and a contact plate 7 (see Fig. 3) e I bedded in insulating substance 6.. The said plate 7 is connected to one terminal of the secondary 8 (Fig. 2) of an induction coil by means of a screw 9-. The other terminal is connected to a ring -10 attached to a metal shaft or pipe 11- 'ournaled in pairs of clamping pieces -12 foods by electric and carrying within the channel a large I number of very yielding contact springs or members 13 Each pair of" clamping p1eces-'12- is adjustable in the space 14 betweenthe two insulating rails -15,

16- and is by screws 17 with hand nuts 18 clamped fast in the desired position. In this manner the springs 13- may be brought in the position relatively to the plate 7-- most suitable to the size (thick-. ness of the fish. -Also the hopper 1- and the-channel 2- may be fixed at a suitable inclination. This is efiected by means of clampingscrevvs 9-- (Fig. 1) passing through a guiding strap 20 attached to the side of the hopper and pressing upon a bar -21 which projects through the strap. The lower end or the bar is pivotally connected to the carrying bracket 22- of the apparatus, and to this bracket the lower portion of the channel '2- is hinged as shown in Fig. 1.

The handles 2, which are made or insulating material and attached to the pipe l1 by means of cross pins '25, are intended for the adjustment of the spring members -l3-. 27- designates a stop ring and 26- the primary of the induction device. l

Of course more bottom contacts may be arranged, so that the fish during its passing down through the channel is subjected to a repeated electric treatment.

Furthermore, the fixed bottom contact 7 may be replaced by a large number of springy contact fingers -3T (Fig. 1) attached to the pipe -4. like the corresponding parts l3 and -11- respectively of the top contacts.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus for sterilization of tacts in such a manner that the fish, etc.,

during its passage down within the channel passes between the said contacts and isthereby subjected to the electric treatment.

2. In an apparatus for sterilization of current of high voltage, especially for killing mite, spores and noxious bacteria on spllt cod, the combination of an inclined channel, contact plates em- I bedded in insulating material in the channel bottomf a large number of yielding springs or yieldingly arranged contact members or fingers projecting into the channel opposite the bottom contacts, a source of electricity of high voltage, and connections between one terminal of said source and the bottom contact plates, and connections between the other terminal and the said members or fingers in such a manner that the fish, etc, during its passage down within the channel passes between the said contacts and is thereby subjected to the electric treatment.

3. In an apparatus for sterilization of foods by electric current of high voltage, especially for killingmite, spores and noxious bacteria on split cod, the combination of an inclined channel,'a number of yielding springs or. yieldingly arranged contact members or-fingers in the bottom of the channel, a large number of yielding springs or yieldingly arranged contact members or fingers projecting into the channel from the top of the same opposite the bottom contacts, a source of electricity of high voltage, and connections between one terminal of said source and the bottom contact members, and connections between the other terminal and the top contact members in such a manner that the fish, etc, during its passage, down within the channel passes between the said contacts and is thereby subjected to the electric treatment.

4. In an apparatus as claimed in claim 2 or 3, the arrangement of a turnable shaft (11) adjustable along the channel, the yielding contact members or fingers (13) being attached side by side on the said shaft, so that by turning and by longitudinal adjustment of the shaft the top contact members may be adjusted relatively to the bottom contact or members (7 or 3).

5. In an apparatus as claimed in claim 4, the arrangement of clamping pieces carrying the shaft (11) and mounted adjustably between and along two rails (15, 16) which may be clamped fast by screws.

6. In an apparatus as claimed in claim 1, the arrangement ofa carrying bracket, to which the lower portion of the apparatus is hinged, whereas the upper hopper-shaped part may be adjusted in height direction and fixed by means of a clamping device (21, 20, 19). I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JACOB HANSSEN.
